I am a researcher working on video compression. As part of my work I need to play back raw (i.e. not compressed) video at the correct frame rate for participants to view as part of a compression quality assessment.
These clips are typically 10 seconds long, at a variety of frame rates up to 60fps and at a variety of resolutions from CIF to 1080p. They usually stored in yuv files of 4:2:0 format.
The problem I have is that 1080p videos cannot play back at the correct frame rate (at least above 24 or 30fps). I assume that this is because the data cannot be loaded from the the HDD quickly enough.
I typically used vlc player, or an obscure windows exe I have called vidview. But this is flexible. I have tried adjusting the file caching and disc caching parameters in vlc player to 10000ms, but this does solve the problem.
I usually use a Windows 7 computer, but this is flexible. I may possibly (or possibly not) already have access to an external RAID box. The desktop machine I am using at the moment has an i7, 8GB memory, a SATA2 HDD.
My question is: would simply playing the videos from a faster drive such as a RAID array or SSD be sufficient to solve the problem?
